I watched your video and I am very surprised. How can somebody invent such a thing? How can I be infected? Is there a chance to block this malware and access my data? Thank you very much.
Ofc you can prevent it. =) Just be careful, once the stuff is encrypted you will have big big issues getting the files back. Set CIS to proactive and if you experience any unknown file google it before allowing it. =)
If unsure, Deny and ask on the forum..
That should got you covered.
And like you don't accept candy from strangers, do not accept files from strangers trying to become your friend either. =)
Use well known sites when DL'ing something.. =) If its not there then its not worth having (IMO unless you got some rare interest).. =)
EDIT:: Infection can happen in many ways, one being you start a file on your own that is infected (common), or visit a infected homepage or opening a file in a mail that is infected.. others ways can include software flaws (could be used by worms) and even directed attacks at you. MSN is a other place were many catch viruses they just open the file "sexyguy.pic.exe" that someone sent them believing it to be whatever the person on the other side said it was.. but surely there are more ways.
People invent stuff all the time.. =) encryption was probably meant to boost security and avoid unauthorized ppl to get hold on info but if something can be used for bad then its usually used for that as well..
